Process control systems, like those used in chemical, petroleum or other industrial enterprises, typically include one or more process controllers communicatively coupled to one or more field devices via analog, digital or combined analog/digital buses. The field devices, which may be, for example, valves, valve positioners, switches and transmitters (e.g., temperature, pressure and flow rate sensors), perform process control functions within the process such as opening or closing valves and measuring process control parameters. The process controllers receive signals indicative of process measurements made by the field devices and then process this information and/or communicate the information to other controllers, workstations, or other components within the control system. Further, multiple control systems may be sub-systems to a higher-level enterprise system in which information from the separate sub-systems may be cross-communicated and/or overseen by a supervisory system.
